Claims

[Scope of utility model registration request]

A boost pressure chamber to which boost pressure is supplied, an output chamber to output an output air pressure signal, an exhaust chamber to discharge exhaust gas flowing out from the output chamber to the atmosphere, and a first diaphragm to insulate the input air pressure signal from the exhaust air. an exhaust valve that is flexibly fixed to a second diaphragm that insulates the exhaust chamber and the output chamber and the first diaphragm and that discharges exhaust gas from the output chamber to the exhaust chamber; an air supply valve that changes an opening area between the air supply pressure chamber and the output chamber in response to the input air pressure signal; and an engagement valve arranged in a direction parallel to the surface of the first diaphragm and eccentric to the center thereof. A pilot relay comprising: a rotation shaft having a shaft; and a pressing means that is engaged with the engagement shaft and presses the surface of the first diaphragm back and forth.
